Its detailed approach has made it a key reference in the history of science and technology and its practical focus contributed to the economic development of mining regions. "Ercker's treatise is the most authoritative contemporary work on 16th-century metallurgy and assaying. Ercker gave a systematic review of methods of testing alloys and minerals and of obtaining and refining various metals as well as methods of manufacturing acids salts and other chemical compounds including saltpeter. He described the apparatus and laboratory equipment used in metallurgy and assaying and gave a detailed account of laboratory methods all of which he himself had used." Norman "Erker's Beschreibung may be regarded as the first manual of analytical and metallurgical chemistry. The only one of Ercker’s works to contain many drawings it presents a systematic review of the methods of testing alloys and minerals of silver gold copper antimony mercury bismuth and lead; of obtaining and refining these metals as well as of obtaining acids salts and other compounds. The last chapter is devoted to saltpeter. Ercker's account of the fact that zinc precipitates other metals from solutions is to be found only in the 1684 and later editions" DSB. “Considering the importance of Ercker’s tratise it is remarkable how little is on record about him. He was inspector-general of the mine of Hungary Transylvania and the Tyrol which position he held under three consecutive emperors in the sixteenth century. He book was highly prized at the time for it was a record of practical experiences and was not burdened with theories and hypotheses. Ferguson. Ferguson 1 244.
